ABSTRACT:
An improved electroviscous fluid formulated with discrete fluids of diverse densities, characterized in that settling of aggregate in functional apparatus is diminished. Aggregate particles having a density between the density of two fluids migrate to the boundary layer of the fluids when the fluids are at rest. By appropriately selecting the volume of the fluids in functional apparatus, the electroviscous fluid aggregate is placed in position for more immediate response when the apparatus is activated by electrical energy.
